INTRODUCTION. 



INSTALLATION PLAN OF EXHIBITS IN THE PALACE OF 

ELECTRICITY. 



BY W. E. GOLDSBOROUGH, CHIEF. 

THE Palace of Electricity occupies a central position on the Exposition 
grounds. It is a fine exhibit structure, pentagonal in shape, and surrounds 
a spacious court. Its east front borders on the Grand Basin, and from its 
southern exposure the Terrace of States and the Cascades are in full view. 

The exhibits within this palace cover all of the modern applications of electricity, 
and each department of education, science and indus.try, associated with electricity, 
is represented in about equal measure. 

The retrospective exhibit is confined very largely to the fine demonstration made 
in honor of Thomas Alva Edison, in Blocks 26 and 27. This exhibit is arranged in 
honor of Mr. Edison on account of the fact that 1904 is the twenty-fifth anniversary 
of the commercial perfection of the incandescent lamp, the agent which has been 
used so effectively in beautifying the Exposition. 

The exhibits wdiich show the commercial development of electricity effectively, 
in that they represent its adaptation in industry, are located in the west end of the 
Palace of Machinery and in the west section of the Palace of Electricity. In the 
Palace of Machinery, large direct connected operating units ranging in capacity up 
to 3500 K. W., and of wide variety, are connected with auxiliary exciting and 
switchboard appliances, as a part of the exhibitors' service power plant, and present 
very imposing and animated pictures. 

In the Palace of Electricity many exhibits in Blocks 3, 4, 5, 6, 7, 8, 9, 14, 15, 
16, and 17, show to what perfection electrical appliances have been brought in 
adapting electric power to the requirements of almost every branch of industry, 
enabling operations involving the use of- large amounts of power to be performed 
with greater certainty, greater regularit}' and greater delicacy of action than have 
ever before been possible. 

In the southwest section of the building will be found the principal exhibits 
illustrating the use of the storage battery in connection with lighting plants, rail- 
w^ays, telephone exchanges and other uses. All of these exhibits are w'orking ex- 
hibits, by which is meant that the machiner}^ is in operation, bringing its adapta- 
bility to the work in hand vividly to the m.ind by actual demonstrations. 

The application of electricity to raihvays has not been overlooked, and in both 
the northwest and southeast quarters of the building will be found fine demonstra- 
tions of the most modern apparatus. - In addition, an extensive series of equip- 
ments are in operation on the experimental test tracks, w^hich lie north of the 
Palace of Transportation, under the supervision of the Department of Elec- 
tricity. Near the west end of the Palace of Forestry, Fish and Game is a compre- 
hensive installation, showing applications of electric track signalling and con- 
trolling apparatus, installed by the German Government as a part of its electrical 
display. 



INTRODUCTION. 



The use of electricit}^ in lighting is also shown in the exhibits in the northwest 
and southeast sections of the building. There are a number of unique devices dis- 
plaj^ed showing the perfection to which the art of decorative and useful lighting 
has been brought through the agency of electricity. 

In the eastern end of the French exhibit in Section 38, is a particularly fine 
arrangement of electric fixtures. These are new and possess high artistic merit, and 
will undoubtedly attract a great deal of attention. 

Instruments of precision for making electrical measurements are shown in ex- 
hibits located in the southeast quarter of the' building. Notable among these is the 
model electrical testing laboratory which has been installed by the National Bureau 
of Standards. The laboratory probably contains one of the finest equipm.ents of 
electrical scientific apparatus that has ever been brought together. 

» In the eastern half of Section 7, where the electrical exhibit of Great Britain 
is located, and in the eastern half of Section 18, in which the Italian exhibit is located, 
are displayed a large and very fine assortment of instruments by European manu- 
facturers. These exhibits are supplemented by a fine display of electrical instru- 
ments of German manufacture, arranged in the Palace of Education. 

In the south and southeast sections are the principal exhibits illustrating the 
use of electricity in the transmission of intelligence. There are two elaborate 
working exhibits, showing the development in the art of telephony, and a number 
of other working exhibits demonstrating automatic control and other specialties 
in this field; one of the most important of these illustrates the use of the tele- 
phone as an aid in enabling the deaf to hear, and in teaching the dumb to speak. 
In this section of the building are also some of the principal wireless telegraph and 
wireless telephone exhibits. The largest of the wireless telegraph stations in the 
Palace of Electricity consists of three towers standing 75 feet in the clear, within 
the building. The height of these towers gives a verj^ good idea of the fine pro- 
portions of this exhibit palace. 

Outside of the Electricity Building there are two wireless telegraph stations. 
One of these consists of a tower 300 feet high, erected near the Press Building, north 
of the Palace of Liberal Arts. The other station consists of a mast 225 feet high, 
erected on the hill south of the Japanese Building and southeast of the Ferris Wheel. 

The exhibits of wireless telephony are also of special interest to the public, as 
they bring ver}' vividly before the observer the wonderful advance that is now being 
made in this department of scientific attainment. 

The other advances which have been made in a scientific way are brought out 
most pointedly in the exhibits in the southeast and north central sections of the 
building. 

The scientific application of electricity to medicine is shown by the exhibits 
in the eastern part of Section 4, where all the modern dcA-elopments for the treat- 
ment of diseases by the aid and use of electricity are presented. 

The advance in chemistry, to which electro-chemistry has contributed so marked 
and extensive a part, especially- within the last few years, is brought out in a very 
striking way in the exhibit of Germany in Section 35. This is probably to the electro- 
chemical engineers, the most interesting exhibit in the Palace of Electricit3^ 

Although in this brief statement many fine installations have not been mentioned, 
an idea is given of the extensive and comprehensive character of the presentation 
of electricitv. 



How to Find an Exhibitor. 



The Palace of Electricity, a ground plan of which accompanies this 
catalogue, is arranged in blocks, with aisles, like the squares and streets 
of a well-planned city. Aisles are lettered and numbered. Blocks are 
numbered, and over each block is suspended a large sign which indicates 
the number of the block beneath. In every case the location of the 
Domestic exhibitor by block and aisle is given The locations of foreign 
exhibit sections are given on the ground plan.
